Richard Giberson and Richard Demaree, Jr, have collected a wide range of time-saving microwave techniques for processing biological samples for evaluation by many different microscopic methods. Described in step-by-step detail by hands-on researchers, these readily reproducible protocols include both optimized classic methods and such state-of-the art techniques as in vivo labeling, formalin fixation of fresh tissue, vacuum processing, and processing for scanning electron microscopy. Each stand-alone microwave method has been handcrafted by a researcher who regularly uses it to ensure processing success and the brightest quality result.
